UNITED STATES GEORGE F. VOIGHT, OF OAKLAND, CALIFORNIA.

FURRING NAIL.

Application filed February 12, 1923.

To all whom it may concern:

Be it known that I, Gnonen F. VOIGHT, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Furring Nail, of which the following is a specification.

My invention relates to furring nails par ticularly useful for securing plasterers wire grilles to the walls of frame buildings, but useful for other purposes as well, such as securing concrete reinforcing wire to road beds, or for securing reinforcing netting of any sort to a surface adapted to be provided with a plastic coating.

One of the objects of the invention is the provision of a furring element carried by a driven element, for securing and spacing the grille a predetermined distanceaway from the surface of the wall to which the plastic material is to be applied.

A further object is the provision of a spacing element formed of sheet metal and having a portion formed into a loop slidably embracing the driven element, the loop having an arm on one side adapted to support a wire grille, the free end of the arm having an extension projecting above said arm and loop and adapted for holding the grille on the arm adjacent the driven element.

Vith the foregoing and further objects and purposes in view which will appear as the description proceeds, myinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention, herein disclosed can be made within the scope'of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a rear elevation, Figure 2 a left-side elevation, Figure 3 a front elevation and Figure 1 a right-side elevation, of a furring nail constructed in accordance with my invention;

Figures 5, 6, 7 and 8, are views in cross section on line -8, Figs. 1, 2, 3 and 1, re spectively Figure 9 is a plan view of the nail with the furring element in the position as indicated in Fig. 1;

Figure 10 is 1010, Fig. 2;

Figure 11 is a rear elevation of the device a sectional view on line Serial No. 618,498.

in its permanent position as applied to a flooring board, a fragmental portion of which being shown in section with the low er end of the nail projected tliereinto, the view also showing a small section of plastic material disposed in the immediate back ground of the nail, which plastic material is adapted to be reinforced by a wire grille a section of which is shown secured to the nail.

Figure 12 is a plan view of the nail and furring element in their permanent position relative to the grille wire, as indicated in Fig. 11.

Figure 13 is a left side elevation of a portion of the furring nail, with a fragment of grille wire secured between portions of the driven element and spacing element;

Figure 1-l is a rear view of the blank stamping from which the spacing element is formed;

Figure 15 is a rear view of the stamping in a modified form;

Figure 16 is a plan view of a modification of the nail.

Referring to the drawings in detail, throughout which like characters designate like parts:

The numeral 1 designates the cylindrical shank portion of an ordinary nail which has at its upper end the usual disk-shaped head 2. j

8 designates aspacing element formed of a strip of sheet metal and comprises an in ner looped portion 4: encircling the lower end of the shank 1, and an outer portion 5 projecting out ardly from said loop portion and provided at its end with an upwardly projecting malleable extension 6.

In the modification shown in Fig. 16, the head 2 is eliminated and the shank 1801116- what lengthened to permit its upper end being bent downwardly to form a downwardly projecting arm A. side elevation of which arm being shown in the upper broken lines in Fig. 2.

. Fig. 15 shows a modification of the spacing element, which is provided along its low er margin with a plurality of downwardly projecting pointed prongs 7, and adjacent its free end with a reinforcing corrugation 8, and a similar corrugation 9 struck in the upper portion of the extension. 6.

10' designates a portion of a wire grille, around and through the meshes of which is spread the plastic composition 12. I

The purpose of the spacing element 3 is to space the grille wires a suitable distance away from the surface of the wall, or the like, to which the device is operatively applied, as well as for securing the wires firmly thereto. And to facilitate the application of the device for thus securing and spacing the wires, I initially lock the loop 4 upon the lower end of the shank 1, as best illustrated in Figs. 1, 2 and 3, by restricting the loop diametrically relative to the shank, whereby the contractile tension of the loop will hold it normally in a fixed position and against accidental movement in any direction relative to the shank, particularly against vertical movement. If desired, the lower end of the shank may be permitted to project a distance below the loop as indicated in Fig. 4.

The device may be readily applied for securing a wire grille :to a support such as a wall surface or the like, by grasping the head end of the nail and projecting its lower end with the spacing element attached thereto through one of the meshes of the grille, then manipulating it to bring one of the wires of the grille between the shank 1 and extension 6 position of wire shown by broken line IO, Fig. 9), and then rotating the nail in a clock-wise direction until the wire 10 (see Figs. 9 and 10) engages both said shank and extension, and then driving the nail forwardly through the loop, against the contractile tensioirof the loop, and the support until the head 2 engages the wire and forces it down firmly against the spacing element and the spacing element seats firmly against the support.

The upper portion of the extension 6, which is adapted to be bent down against the grille wire 10 (see Figs. 11, 12, 13) and thereby assist the head 2 in holding it securely against the intermediate section of the spacing element, may be separately engaged and bent down by the driving tool after the nail has been driven home into the support, or, if preferred, it may be engaged and bent down simultaneously with the driving of the nail.

In the modification shown in Figs. 2 and 16, I employ a shank member somewhat longer than the one used in the preferred form, and instead of forming the head 2 at its upper end I simply bend the end over to one side so as to form a downwardly projecting arm 2, which arm, when the shank is driven a proper distance clownwardly through the loop 4, will engage and hold the wire 10 against the spacing element 1n approximately the same manner as the head 2- wonld do if employed.

7 In the modified form. of the spacing element shown in 15, I provide a plurality of downwardly projecting pointed prongs 7 struck into the lower edge of the spacing element 3, which are intended to project themselves a sutlicient distance into the surface of the support to which the device is secured to prevent any possible reverse rotation of the spacing element during the driving of the nail.

The corrugations 8 and 9, are intended to stiffen these portions and thereby prevent accidental collapsing thereof when the upper end of the extension 6 is struck for bending it down upon the wire 10. The corrugations are further intended to insure the bending of the extension 6 along a line extending across its base in engagement with said wire, and in order to accomplish which the corrugations do not extend across said line.

The corrugations 8 and 9 are preferably arcuated in cross section and are struck rearwardly out of the plane of the outer portion 5, however, if desired, they may be made so as to project out upon the op posite side thereof.

I claim 1. In means of the character described, the combination with a driven element, of a spacii'ig element locked on said driven element and forming an integral part thereof, the spacing element having a portion projecting laterally outwardly from said driven element, the free end of said portion provided with, an upwardly extending memher.

2. In, a device of the character described, in combination, a nail element, a spacing element formed of sheet metal and having one end embracing a portion of said nail element and its other end projecting horizontally outwardly therefrom, and an upwardly projecting extension on the free end of said spacing element.

In a device of the character described, the combination with a horizontally disposed wire, of a nail element having a shank member engaging one side of said wire, a spacing element supporting said wire from its lower side and having one end encircling Said shank member and its other end projecting horizontally outwardly therefrom, and an extension on the free end of said spacing element disposed to engage said wire on the opposite side of said shank member.

In combination, a spacing element formed of sheet metal and embodying a body portion formed with an eye at one end, the other end of said portion provided with an upwardly projecting extension, and a. driven element having a shank portion projecting into said eye and attached thereto.

5. In combination, a spacing element formed of sheet metal and embodying a body portion formed with an eye at one .end, the opposite end thereof provided with an upwardly projecting extension, and a driven element having a shank portion projecting into said eye and normally locked therein by the diametrical contractile tension of the walls forming said eye bearing against said shank portion.

6. In combination, a driven element embodying a shank portion having its upper end formed into a hook, and a spacing element formed of sheet metal and having one end curled back to form a cylindrical loop embracing the lower portion of said shank portion and normally locked thereon, said spacing element operatively slidable along said shank portion for coacting with said hook for holding a wire therebetween.

7. In means of the character described, a driven element, and a spacing elementintegrally attached to said driven element, said spacing element having an arm projecting outwardly from said driven element, said arm having an upwardly projecting extension at its free end, said extension adapted to be operatively bent to one side along a plane extending along one side of said driven element.

8. In means 01' the character described, a driven element comprising a shank member having a lateral projection at its upper end, and a spacing element formed or a single strip of sheet metal and con'iprising, a loop portion slidably embracing said shank memher, an arm on said loop portion extending laterally outwardly from said shank memher, and an extension on the free end of said arm projecting above the arm and said loop portion, said extension adapted for holding a grille wire on said arm below said lateral projection of said shank member.

9. In means of the character described, a driven element comprising a shank mem her having a head at its upper end, and a spacing element formed of sheet metal and comprising, a body portion siidably attached to said shank member, an arm extending outwardly from said body portion, and an extension on the outer end of said arm, said head and arm cooper-able for binding a grille wire therebetween when said spacing element is moved along said shank member a proper distance vertically, said extension projecting substantially above said arm and body portion and adapted for limiting the movement of said grille wire on said arm in a direction away from said shank member, said extension being free from engagement with said shank member.

In testimony of the foregoing being my own, I have hereunto aflixed my signature this 5th day of February, 1923.

GEORGE l VOIGHT.
